Intermittent fasting diets might trigger fertility issues, based on new analysis.

The scientists behind the research checked out female and male Zebrafish - Danio rerio - to seek out out what occurs when they're uncovered to meals throughout and after a interval of fasting.

And they discovered that a number of the destructive results on eggs and sperm high quality had been seen after the fish returned to their regular ranges of meals consumption.

Female Zebrafish noticed a rise within the variety of offspring they produced however noticed a drop in egg and offspring high quality, and the male's sperm additionally decreased in high quality.

Dr Edward Ivimey-Cook, from the University of East Anglia's School of Biological Sciences, stated the findings emphasised the significance of contemplating "not just the effect of fasting on body maintenance but also on the production of eggs and sperm".
